g still amatter of uncertainty. Chronic myelitis is in some cases due tosyphilis, and then it may be either a diffuse process advancing into thecord from the periphery, attended by degeneration which appears firstin the lateral columns of the cord and gives rise to the symptoms ofspastic paraplegia (the spinal syphilis of Erb), or it may be a trans-verse process due to syphilitic endarteritis in the vessels at a certainlevel, or to the appearance of syphilitic indurations with infiltration ofround cells in both white and gray matter. Such syphilitic infiltra-tions may be very irregular in their distribution; may be confined toone segment of the cord, causing a chronic transverse myelitis; may CEBONIC MYELITIS. 411 be limited to one or more columns of the cord, causing symptomsresembling focomotor ataxia or lateral sclerosis of one or both sides;may cause a unilateral lesion, producing symptoms of Brown-S6quardparalysis, or may be irregularly disseminated throughout the cord.

(Schmaus-Sacki.) Chronic myelitis is sometimes due to pernicious anaemia, the changesin the cord which occur in the course of this disease being diffuse inlocation and slow in development^ (see page 393). Slow poisoning byergot or lathyrus may cause chronic myelitis. Chronic myelitis is usually a disease of adult life, persons of the ages from twenty-five to forty-five years being more liable to the affection; it is about equally prevalent in males and females. It is possibly traceable in some cases to an inherited neuropathic tendency. It is, in F.
